All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

Embodiment 1

The embodiment of the present invention provides a method for highlighting a party of interest in video conferencing. As shown in FIG. 1, the method includes the following steps:

101. Receive audio and video signals sent by multiple conferencing terminals.

In video conferencing, each participant has a conferencing terminal, where the conferencing terminal may send audio and video signals of the participant to conferencing terminals of other participants, and may also receive audio and video signals sent by the other conferencing terminals.

In this embodiment, in video conferencing, the conferencing terminal A configured for the participant A may receive audio and video signals sent by multiple other conferencing terminals in the video conferencing.

102. Convert the received audio and video signals sent by the multiple conferencing terminals into multiple independent video images corresponding to the multiple conferencing terminals, and display the multiple video images through a display device.

In this embodiment, the conferencing terminal A may convert the received audio and video signals into video images, and display the video images on a display device of the conferencing terminal A. It should be noted that the process of converting and displaying video images is based on the prior art, and is not further described herein.

By performing this step, the participant A may see video images of other participants through the display device of the conferencing terminal A.

103. Obtain video image display priority signals, and adjust display factors of the multiple video images according to the obtained video image display priority signals, so that the multiple video images present different visual characteristics in the display device.

When the display device of the conferencing terminal A displays the video images of the other participants, the conferencing terminal A may obtain video image display priority signals, where the video image display priority signals may indicate the priorities of the video images displayed by the display device.

Optionally, a user, namely, the participant A, may perform a selective input on the multiple video images, for example, click a video image of a participant of interest to the user; in this case, the selective input of the participant A is the video image display priority signals. The conferencing terminal A adjusts display factors of the multiple video images directly according to the received selective input of the participant A, namely, the video image display priority signals, so that the multiple video images present different visual characteristics in the display device. Optionally, a video image selected by the selective input has the highest video image priority, and video images that are not selected have priorities lower than that of the selected video image. A processor may enhance, according to the priority, display factors of the video image that has the highest video image priority signal and weaken display factors of the other video images.

Furthermore, as shown in FIG. 2, the method further includes the following:

104. Generate video image display priority signals.

In this embodiment, the conferencing terminal A may generate video image display priority signals, so that the conferencing terminal A obtains the video image display priority signals, and adjusts the display factors of the multiple video images according to the obtained video image display priority signals, so that the multiple video images present different visual characteristics in the display device.

Optionally, two methods for generating the video image display priority signals exist.

The first method is: receiving the selective input performed by the user on the multiple video images, and generating the video image display priority signals according to the selective input, where the video image selected by the selective input has the highest video image priority and the video images that are not selected have the priorities lower than that of the selected video image.

Optionally, in this embodiment, the user, namely, the participant A, may perform the selective input on the multiple video images displayed by the display device of the conferencing terminal A. A specific selective input manner may be hovering the mouse pointer and right-clicking or left-clicking a video image of a party of interest selected by the user, or may also be pressing a video image of a party of interest, which is selected by the user, with a finger for a long time if a display of the video terminal is a touch screen, which is not limited herein. FIG. 3 shows that when a user presses a video image of a party of interest, participant B, which is selected by the user, with a finger for a long time, the conferencing terminal A may generate the video image display priority signals according to an input of the user. Optionally, the conferencing terminal A may set the video image selected by the selective input to have the highest video image priority, and set the video images that are not selected to have the priorities lower than that of the selected video image.

Correspondingly, the conferencing terminal A may adjust the display factors of the multiple video images according to the received video image display priority signals. The conferencing terminal A enhances the display factors of the video image that has the highest video image priority signal, and weakens the display factors of the other video images.

When the conference is a three-dimensional (3D) video conference, the conferencing terminal may generate a 3D virtual conferencing environment, and display the 3D virtual conferencing environment through the display device of the conferencing terminal, where the multiple video images are respectively displayed in the 3D virtual conferencing environment. As shown in FIG. 3, when the participant A presses a video image of a party of interest, participant B, which is selected by the user, with a finger for a long time, the conferencing terminal A generates the video image display priority signals according to the selective input of the user, where the video image display priority signals indicate that the video image selected by the selective input has the highest video image priority and that the video images that are not selected have the priorities lower than that of the selected video image. The conferencing terminal A enhances the display factors of the video image that has the highest video image priority signal according to the video image display priority signals, and weakens the display factors of the other video images. Optionally, as shown in FIG. 4, the conferencing terminal A may arrange the video image that has the highest video image priority signal to be in front of the other video images in the 3D virtual conferencing environment. Thereby, the video image of a party of interest, participant B, selected by the user is nearer to the user, which is helpful for the user to pay attention to a video image of the party of interest among the participants and enhances conference efficiency.

Certainly, the participant A may also manually drag the video image of the participant B of interest to the participant A, and move the video image to the front of the other video images, so that the video image of the participant B of interest to the user is nearer to the user, which is helpful for the user to pay attention to the video image of the party of interest among the participants.

Furthermore, optionally, the conferencing terminal may further automatically adjust resolutions of the video images according to position relationships of the video images in the 3D virtual conferencing environment, that is, adjust the resolution of the front most video image in the 3D virtual conferencing environment to a first resolution, and adjust resolutions of video images other than the front most video image to a second resolution, where the first resolution is higher than the second resolution. That is to say, the video image of the participant B of interest to the user is adjusted to a video image of the first resolution to make the video image clearer; and the video images of the participants other than the video image of the party of interest which are located behind in FIG. 4 are adjusted to video images of the second resolution to reduce definitions of the video images. By performing this step, the video image of the party of interest can be highlighted more effectively, so that the user can more effectively pay attention to the party of interest selected by the user; and at the same time, the resolutions of the video images are adjusted, so that a bandwidth for receiving the video image of the party of interest is increased and a bandwidth for receiving the video images of the participants other than the party of interest is reduced, thereby effectively utilizing a bandwidth of a network.

The second method is: detecting audio energy in the audio and video signals sent by the multiple conferencing terminals; and determining audio and video signals sent by the conferencing terminals, of which the audio energy is the highest or the audio energy is higher than a predetermined audio energy threshold, and generating the video image display priority signals according to the determined audio and video signals, where a video image display priority of the audio and video signals of which the audio energy is the highest or the audio energy is higher than a predetermined audio energy threshold is highest.

In step 101 of this embodiment, the conferencing terminal A receives the audio and video signals sent by the multiple conferencing terminals; the conferencing terminal A detects energy of the audio and video signals after receiving the audio and video signals. The video image display priority signals indicate generated according to the audio energy in the audio and video signals, that is, the video image display priority of the audio and video signals of which the audio energy is the highest or the audio energy is higher than a predetermined audio energy threshold is highest. Thereby, a video image of a speaker or a participant whose voice is the loudest among the participants has the highest video image display priority. The conferencing terminal A enhances the display factors of the video image that has the highest video image priority signal according to the video image display priority signals, and weakens the display factors of the other video images. Optionally, as shown in FIG. 4, the conferencing terminal A may arrange the video image that has the highest video image priority to be in front of the other video images in the 3D virtual conferencing environment. Thereby, the video image of the speaker or the participant whose voice is the loudest is nearer to the user, which is helpful for the user to focus on the video image of the speaker or the participant whose voice is the loudest, and enhances the conference efficiency.

In the preceding method, if the video image of which the audio energy is the highest has the highest video image priority, only one such video image exists and if the video image display priority of the audio and video signals of which the audio energy is higher than a predetermined audio energy threshold is highest, multiple such video images exist.

Correspondingly, the conferencing terminal may adjust the display factors of the multiple video images according to the obtained video image display priority signals, which can be: enhancing the display factors of the video image that has the highest video image priority signal, and weakening the display factors of the other video images. When the conference is a 3D video conference, the conferencing terminal may generate a 3D virtual conferencing environment, and display the 3D virtual conferencing environment through the display device, where the multiple video images are respectively displayed in the 3D virtual conferencing environment. Optionally, as shown in FIG. 3, the conferencing terminal A may arrange the video image that has the highest video image priority signal to be in front of the other video images in the 3D virtual conferencing environment. Thereby, the speaker or the participant whose voice is the loudest is highlighted and becomes a party of interest to which the user, namely, the participant A, needs to pay attention to, and the video image of the party of interest is nearer to the user, which is helpful for the user to pay attention to the video image of the speaker or the participant whose voice is the loudest and enhances the conference efficiency.

Furthermore, optionally, the conferencing terminal may further automatically adjust resolutions of the video images according to position relationships of the video images in the 3D virtual conferencing environment, that is, adjust the resolution of the front most video image in the 3D virtual conferencing environment to the first resolution, and adjust resolutions of the video images other than the front most video image to the second resolution, where the first resolution is higher than the second resolution. That is to say, the video image of the party of interest is adjusted to the video image of the first resolution to make the video image clearer; and the video images of the participants other than the video image of the party of interest which are located behind in FIG. 4 are adjusted to the video images of the second resolution to reduce definitions of the video images. By performing this step, the video image of the party of interest can be highlighted more effectively, so that the user can more effectively pay attention to the speaker or the participant whose voice is the loudest; and at the same time, the resolutions of the video images are adjusted, so that the bandwidth for receiving the video image of the party of interest is increased and that the bandwidth for receiving the video images of the participants other than the party of interest is reduced, thereby effectively utilizing bandwidth of the network.

In the preceding two methods provided by the embodiment of the present invention, the first method is applicable to a manual mode, in which the video image of the party of interest to which the user wants to pay attention is selected manually; and the second method is applicable to an automatic mode, in which the conferencing terminal automatically selects the video image of the party of interest. In actual applications, the user may select the manual mode or automatic mode as required to perform a video conference.

The embodiment of the present invention provides a method for highlighting a party of interest in video conferencing. Received audio and video signals sent by multiple conferencing terminals are converted into multiple independent video images corresponding to the multiple conferencing terminals, and the multiple video images are displayed through a display device; and display factors of the multiple video images are adjusted according to obtained video image display priority signals, so that the multiple video images present different visual characteristics in the display device. Thereby, a participant of interest to a user can be effectively highlighted, and conference efficiency is enhanced.
